Edge theory approach to topological entanglement entropy, mutual information and entanglement negativity in Chern-Simons theories
- X. Wen, S. Matsuura, S. Ryu
- Physics
- 28 March 2016
We develop an approach based on edge theories to calculate the entanglement entropy and related quantities in (2+1)-dimensional topologically ordered phases. Our approach is complementary to, e.g.,…
Floquet conformal field theory
- X. Wen, Jie-qiang Wu
- Physics
- 30 April 2018
Given a $generic$ two-dimensional conformal field theory (CFT), we propose an analytically solvable setup to study the Floquet dynamics of the CFT, i.e., the dynamics of a CFT subject to a periodic…
Emergent Spatial Structure and Entanglement Localization in Floquet Conformal Field Theory

- 14 August 2019
We study the energy and entanglement dynamics of $(1+1)$D conformal field theories (CFTs) under a Floquet drive with the sine-square deformed (SSD) Hamiltonian. Previous work has shown this model…
Entanglement negativity after a local quantum quench in conformal field theories
We study the time evolution of the entanglement negativity after a local quantum quench in (1+1)-dimensional conformal field theories (CFTs), which we introduce by suddenly joining two initially…
Holographic entanglement renormalization of topological insulators
We study the real-space entanglement renormalization group flows of topological band insulators in (2+1) dimensions by using the continuum multiscale entanglement renormalization ansatz (cMERA).…
Topological entanglement negativity in Chern-Simons theories
A bstractWe study the topological entanglement negativity between two spatial regions in (2+1)-dimensional Chern-Simons gauge theories by using the replica trick and the surgery method. For a…
Population inversion induced by Landau–Zener transition in a strongly driven rf superconducting quantum interference device
- Guozhu Sun, X. Wen, Peiheng Wu
- Physics
- 9 March 2009
Microwave resonances between discrete macroscopically distinct quantum states with single photon and multiphoton absorption are observed in a strongly driven radio frequency superconducting quantum…
Evolution operators in conformal field theories and conformal mappings: Entanglement Hamiltonian, the sine-square deformation, and others
By making use of conformal mapping, we construct various time-evolution operators in (1+1) dimensional conformal field theories (CFTs), which take the form $\int dx\, f(x) \mathcal{H}(x)$, where…
Entanglement dynamics of a superconducting phase qubit coupled to a two-level system
- Guozhu Sun, Zhongyuan Zhou, Bo Mao, X. Wen, Peiheng Wu, Siyuan Han
- Physics
- 13 November 2011
We report the observation and quantitative characterization of driven and spontaneous oscillations of quantum entanglement, as measured by concurrence, in a bipartite system consisting of a…
Entanglement Hamiltonian evolution during thermalization in conformal field theory
In this work, we study the time evolution of the entanglement hamiltonian during the process of thermalization in a (1+1)-dimensional conformal field theory (CFT) after a quantum quench from a…
